摘要: 利用有限元耦合場數值模擬計算方法進行了高溫鋼板純水噴霧冷卻的模擬,研究了射流出口高度和鋼板表面溫度對換熱系數的影響.模擬結果表明:在其他參數不變的情況下,隨噴射距離(在200~500mm范圍內)的減小,換熱系數總體呈增加趨勢;隨鋼板表面溫度(在1050~200K范圍內)的增加,換熱系數總體呈減小趨勢.

Abstract: Spray cooling of a high-temperature steel plate was simulated by using finite element method. The effects of surface-to-nozzle distance and steel plate's surface temperature on spray cooling heat transfer coefficient were analyzed. The simulation results show that on condition that other parameters retain constant, the heat transfer coefficient increases totally with decreasing jet space (200~500mm) and decreases totally with the surface temperature increasing when the surface temperature of the plate in 1050~1 200K.
